According to Kuo, Apple will be scaling up iPhone production 120-150 million units in the second half of 2017. If true, this would would be well above the 110-120 million units Apple ordered of its bestselling iPhone 6 generation handsets.

Kuo claims this “unprecedented” demand will be centered around the myriad big improvements Apple has planned for its next-gen iPhone series.

The rumored decision to adopt a glass chassis for the next-generation iPhone is reportedly fueled by a desire to improve wireless charging, another key feature supposedly coming to Apple’s 2017 phone.

The report comes from notable Apple analyst Ming-Chi Kuo, who claims that all 2017-era iPhones will boast the long-awaited wireless charging tech.

Earlier this year, a report from Bloomberg said Apple was working with partners to overcome current technical barriers with wireless technology, including loss of power over distance. If successful, innovation could make Apple’s version of wireless charging considerably more advanced than Samsung’s.
